Otto Neurath: Use

“All content of science, and also their protocol statements that are used for verification, are selected on the basis of decisions and can be altered in principle.”

“We are like sailors who on the open sea must reconstruct their ship but are never able to start afresh from the bottom. Where a beam is taken away a new one must at once be put there, and for this the rest of the ship is used as support. In this way, by using the old beams and driftwood the ship can be shaped entirely anew, but only by gradual reconstruction.”

“Only one language comes into question from the start, and that is the physicalist. One can learn the physicalist language from earliest childhood. If someone makes predictions and wants to check them himself, he must count on changes in the system of his senses, he must use clocks and rulers, in short, the person supposedly in isolation already makes use of the ‘intersensual’ and ‘intersubjective’ language. The forecaster of yesterday and the controller of today are, so to speak, two persons.”

“The primordial forms of all sciences, taken back beyond the rise of writing, lie ultimately in the magic of prehistory. Just as modern man wants to indicate what consequences his actions will have, so also a man who grows up in the magical way of life seeks to find a ground for everything and to find consequences of his action. Magic as a more or less clearly formulated system of tenets shot through with emotional elements, can become independent only when magicians, acting as specialists, proclaim the consequences of certain customs, either esoterically,. e. g. at certain rituals, or exoterically as popular education. The magicians tell what cases are to count as 'equal', and when certain measures shall be used”

“The members of the Vienna Circle (Moritz Schlick, Rudolf Carnap, Philipp Frank, Hans Hahn, Herbert Feigl, Fritz Waismann, Kurt Godel, Otto Neurath and others) are working out a ‘Logical Empiricism’. Following Ernst Mach and Poincaré, but above all Russell and Wittgenstein, all the sciences are treated uniformly. Carnap’s Logischer Aufbau der Welt (1928) shows in which direction future systematic work will move. Wittgenstein’s Tractatus Logico-Philosophicus (1921) clarified, among other things, the position of logic and mathematics; besides the statements that make additions to what is meaningful, there are the ‘tautologies’ that show us which transformations are possible within language. By its syntax the language of science excludes anything that is meaningless from the very beginning.”

“The universal jargon, in the sense explained above, is the same for the child and for the adult. It is the same for a Robinson Crusoe as for a human society. If Robinson wants to join what is in a protocol of yesterday with what is in his protocol today, that is, if he wants to make use of language at all, he must make use of the ‘intersubjective’ language. The Robinson of yesterday and the Robinson of today stand precisely in the same relation in which Robinson stands to Friday.”
